You simplify every fraction the same way. You divide the numerator
and denominator by a common factor. When they have no common
factor except ' 1 ', then the fraction has reached its simplest form.
The factors of 62 are 1, 2, 31, and 62 .
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 .
The COMMON factors are 1 and 2 .
Divide numerator and denominator by 2, and you have 31 /20 .
That's the simplest form of the fraction, but it's still an 'improper' fraction,
that is,a fraction that's greater than ' 1 ' because the numerator is greater
than the denominator.
You can take 20 of the 20ths and call them ' 1 '. Then you have 1 and 11/20 .
You can't get any simpler or more proper than that.
